Here's an amusing bug in FONATest, line 89, given the comment

char imei[15] = {0}; // MUST use a 16 character buffer for IMEI!

should of course be

char imei[16] = {0}; // MUST use a 16 character buffer for IMEI!

Thanks for this library and the examples! Very useful!

Hello,

Is MQTT support available on this device?

I would like to publish via SSL encrypted MQTT. If this library and module could be a transparent GPRS connection it would be perfect.

Recently purchased a module and found that:

    if (! sendParseReply(F("AT+CPMS?"), F("\"SM\","), &numsms) ) return -1;
  } else {
    if (! sendParseReply(F("AT+CPMS?"), F("+CPMS: \"SM_P\","), &numsms) ) return -1;
  }

https://github.com/adafruit/Adafruit_FONA_Library/blob/master/Adafruit_FONA.cpp#L483

needs to be changed to:

    if (! sendParseReply(F("AT+CPMS?"), F("\"SM\","), &numsms) ) return -1;
  } else {
    if (! sendParseReply(F("AT+CPMS?"), F("+CPMS: \"SM\","), &numsms) ) return -1;
  }

I don't know the scope of this issue or if I have a one off firmware rev on the SIM800 but might be worth looking into.

It might be handy to add travis-ci to this lib to make sure the examples compile.

Was this define set purposely or by coincidence?
File: includes/FONAConfig.h

I just updated this library via Arduino GUI and got all the debug messages....

Hi,

I am desperate to get my SIM800L module (http://www.ebay.co.uk/itm/SIM800L-GPRS-GSM-Module-Board-Quadband-QUAD-BAND-Antenna-for-MCU-Arduino-/321992759287) sending POST requests for a long period of time... Sometimes it stops after 100 requests in a row, sometimes 300 so it's really weird.

Everytime I run it, it sends the request for a while (between 1 and 3 hours) and suddenly stops on these AT commands:
---> AT+HTTPINIT
<---

OK
When it works the OK is on the same line and it goes on to the next AT command.
---> AT+HTTPTERM
<--- ERROR
---> AT+HTTPINIT
<--- OK
---> AT+HTTPPARA="CID"
<--- OK
---> AT+HTTPPARA="UA"
<--- OK
---> AT+HTTPPARA="URL"
<--- OK
---> AT+HTTPPARA="CONTENT"
<--- OK
---> AT+HTTPDATA=1221,10000
<--- DOWNLOAD
<--- OK
---> AT+HTTPACTION=1
<--- OK
Status: 201
Len: 0
---> AT+HTTPREAD
<--- OK
---> AT+HTTPTERM
<--- OK

I thought it was a powering problem so I connected the module to the VIN pin of my arduino mega via a buck converter but the problem is still here!

Does anybody have any idea what could be wrong? I can send you the code if needed.

Many thanks in advance

Working with an Arduino Uno and a FONA 3G. I was following instructions to set baud to 4800. But thought, gosh, I remember when 9600 baud was fast, 4800? So I looked a little harder and noticed this error message in the FONA3G_setbaud sketch:
---> AT+IPREX=49664
Delved further and method ::setBaudRate has baud defined as unsigned int 16 which isn't large enough to store 115200 (only 65535). I change to int32_t and seems to be fine now. Probably ought to be a string and maybe improved with further validating values, the 5320 will provide a list of valid values with AT+IPREX?

I am just browsing the source, but based on my own experiments with the SIM800L I think there is an error in ::getNumSMS()

On line 482 of Adafruit_FONA.cpp we see the following code

if (sendParseReply(F("AT+CPMS?"), F(FONA_PREF_SMS_STORAGE ","), &numsms))

But shouldn't that be sending "AT+CPMS=" and not AT+CPMS? a quick test with my own SIM800L module shows that using ? instead of = generates ERROR.

Am I missing something?

FONAtest_gprs.txt

The fona.GPRSState command returns true as soon as the network status changes from a disconnected to a connected state, even if the fona.enableGPRS(true) function has not yet been called.

The issue may be in the modem itself, as the AT+CGATT? command returns 1 in this case when it should not.

This issue prevents me from making a sketch that automatically reconnects GPRS if it unexpectedly goes down. This is because the fona.GPRSState function doesn't accurately report when GPRS is up and down.

I am attaching a version of the FONAtest sketch that has an extra command (D) to run fona.GPRSState. It can be used to validate this bug. You will see that 'D' returns '0' while the modem is trying to connect to the network. However, upon connecting, 'D' begins returning '1' even though the 'G' (Enable GPRS) command has not yet been run.

• Arduino board: UNO
• Arduino IDE version (found in Arduino -> About Arduino menu): 1.8.3

APN Settings appear to need to be burned into the code at runtime and don't support being set from variables or values stored in the EEPROM. I need to be able to send an SMS containing the APN settings to the device and have it store the values and have them persist through a reboot.
There's quite possibly something obvious I'm missing here but I've not been able to solve this one.

Hi there, if i use the library with only a FONA connected, everything works good. But, as a arduino nano has only one hardware serial and i want to use that for external gps, i have to switch off debugging in FONAConfig.h. This works ofcause, but without debug informations it's difficult to program and sadly my C is not so good so i could not change the DebugStream to a SoftwareSerial my sketch creates for debugging.

Can anybody help here?

Just downloaded FONA_Library,
Getting error in compilation

In member funtion 'boolean Adafruit_FONA::TCPsend(char*, uint_t);

In my code I use Wifi and GSM to send data over the internet. So my code works this way if wifi fails it switches to GSM and if wifi is available again then it will switchback to wifi and now if wifi fails again it is unable to switch to GSM as enableGPRS function returns false every time.

Any help would be appreciated.

I am reading the FONAtest.ino and it says the SIM card IMEI a lot, as far as I know, the IMEI is a module's unique number, so even if the user changed the SIM, the IMEI stays the same.

The IMEI comes printed in the SIMCOM module, so I think the text under the examples should reflect that.

Hello,

Thank you for opening an issue on an Adafruit Arduino library repository. To
improve the speed of resolution please review the following guidelines and
common troubleshooting steps below before creating the issue:

• Do not use GitHub issues for troubleshooting projects and issues. Instead use
  the forums at http://forums.adafruit.com to ask questions and troubleshoot why
  something isn't working as expected. In many cases the problem is a common issue
  that you will more quickly receive help from the forum community. GitHub issues
  are meant for known defects in the code. If you don't know if there is a defect
  in the code then start with troubleshooting on the forum first.

• If following a tutorial or guide be sure you didn't miss a step. Carefully
  check all of the steps and commands to run have been followed. Consult the
  forum if you're unsure or have questions about steps in a guide/tutorial.

• For Arduino projects check these very common issues to ensure they don't apply:

  • For uploading sketches or communicating with the board make sure you're using
    a USB data cable and not a USB charge-only cable. It is sometimes
    very hard to tell the difference between a data and charge cable! Try using the
    cable with other devices or swapping to another cable to confirm it is not
    the problem.

  • Be sure you are supplying adequate power to the board. Check the specs of
    your board and plug in an external power supply. In many cases just
    plugging a board into your computer is not enough to power it and other
    peripherals.

  • Double check all soldering joints and connections. Flakey connections
    cause many mysterious problems. See the guide to excellent soldering for examples of good solder joints.

  • Ensure you are using an official Arduino or Adafruit board. We can't
    guarantee a clone board will have the same functionality and work as expected
    with this code and don't support them.

Can we update the function for setting the PWM of the buzzer? The Feather FONA doesn't have a dedicated PWM pin for the buzzer so it'd be nice to be able to set a pin for this for Feather FONA use.

• Arduino board: Adafruit Feather FONA
• Arduino IDE version 1.8.9

The timeout for the pickup() method is only the default timeout (500ms). Sometimes, this timeout is not enough, the response comes shortly after the method times out and returns false.

The SIM800 AT command manual specifies a maximum response time of 20s for voice calls. I therefore suggest changing the timeout for this method to 20s. Optionally, a timeout parameter could be added with 20s as default in case someone needs a shorter timeout.

Similar issues could affect other AT commands used, i did not check it yet.

• FONA device: Adafruit FONA - Mini Cellular GSM Breakout uFL Version

After setting up the FONA and Arduino as described in the tutorial and "logging on" to the Arduino's serial connection using the screen command above, certain commands like that take input like r for "Read SMS #" work but those that use the readline function like c for "make phone Call" do not. Apparently the screen utility when used like so only sends ASCII carriage returns (0xD) and not line feeds (0xA). I have a PR incoming that treats those chars as equal line enders.

unsolicited messages are annoying and confuse the parser - so maybe have a flag in readline() that if its an unsolicited message, retry the read?

It appears that only short commands e.g. three characters ones like ATI work. Longer commands e.g. AT+GSN (to get the IMEI) don't work.

Hello! I have recently bought a FONA shild V2 with SIM R14.18 and I am encountering blockings when using the function "callerIdNotification" with last code (version of Jan. 21st, 2016).

I apologize for the banality of the request , where can I find the list of the library's commands ?

Hi,

I experienced some seriuos problems while debugging an issue while using the GET method to an nginx server.

The issue was that even if my URL was http, the library would force it to https. I'm not sure what was causing this, but after browsing the .cpp i only found this function on Adafruit_FONA.cpp at the Adafruit_FONA::HTTP_setup function.

To fix this issue I made a minor adjustment to the Adafruit_FONA.cpp:

`
// HTTPS redirect
if (httpsredirect) {
if (! HTTP_para(F("REDIR"),1))
return false;

if (! HTTP_ssl(true))
  return false;

}else{
if (! HTTP_ssl(false))
return false;
} `

This is probably not the best place to insert my little patch but I suggest you somehow manage to prevent SSL when not required.

Hi,

The TCPread call is defined as:

uint16_t Adafruit_FONA::TCPread(uint8_t *buff, uint8_t len)

what happens when you have more than 256 bytes to read ? Or that never happens ?

Another thing is that

uint16_t Adafruit_FONA::TCPavailable(void)

is able to return a length greater than 256 to read from... should we read 256 bytes at a time ?

Thanks!

The GPS test and FONA test 3D location fix hasn't worked for 2 different 3G FONA boards I've purchased (with active antennae). Is this just a code issue with the 3G? The SMS and everything else is working fine. Where are the AT commands given as they aren't in the sketch?

Call TCPClose(). The method expects AT+CIPCLOSE response to be OK.

TCPclose should be modified to the one below.

boolean Adafruit_FONA::TCPclose(void) {
  return sendCheckReply(F("AT+CIPCLOSE"), F("CLOSE OK"));
}

AT+CIPCLOSE Response according to SIM800 manual is CLOSE OK and not OK

The original version of TCPclose returns true only if the AT+CIPCLOSE responds with OK due to ok_reply being used:

boolean Adafruit_FONA::TCPclose(void) {
  return sendCheckReply(F("AT+CIPCLOSE"), ok_reply);
}

I miss UDP functionality in the library, I am coding it myself right now but I am facing a little dilema.

Most TCP methods are the same as the UDP ones, all the same code for sending, closing etc.. Just the connection part is different, where one needs a "TCP" parameter when opening a connection with the server and the other a "UDP".

I think the correct thing to do is to rename the TCP methods to TCPIP or something similar and let then be generic and the user selects if it's supposed to be TCP or UDP. The problem with this is breaking legacy code compatibility.

So what do you think it's best:

1- To add new methods for UDP, being just a copy of the TCP ones (with the exception of the connect method).

2- Make generic methods that will handle both TCP and UDP and erase the current TCP methods, which can lead to problems in older codes.

3- Do option 2 but keep the old TCP methods, marked as legacy code, to prevent breaking old code functionality.
personally think option 3 is the one to go.

Please!

If you use the function getGPS(uint8_t arg, char *buffer, uint8_t maxbuff) but set maxbuff to 0, len will always be 255 (unless somehow strlen(p) > 255). This results in other parts of ram being overwritten which has a high chance of breaking running code.

uint8_t len = max(maxbuff-1, strlen(p));

Code excerpt from

You may ask, "If you're not storing the data to some location, why do you care?" or "Why would you ever set it to 0?". I'm specifically just using the debug outputs to get the data I care about but this doesn't change the fact that this function has the ability to easily break your code.

While we're at it, buffer should be allowed to be nullptr and have the same effect.

There is also an issue with using max() here as pointed out in #39.

It would be helpful to add FONA lib parsing for the GPS and GSMloc data. Maybe parse them into a common format and store them as floats on the instance of the class?

Hi,

how can I read or send SMS with umlauts (ä, ö, ü) or special characters like "€"?
Thanks for your support.

Regards, Markus

Adafruit_FONA.cpp line 712:

uint8_t len = max(maxbuff-1, strlen(p));

Should call to max be a call to min? Example call to buffer uses a length of 80. Data returned is length 89. This call will copy 89 characters to an 80 character buffer.

Made a quick branch of the library that in theory supports hardware serial here: https://github.com/adafruit/Adafruit_FONA_Library/tree/hardware_serial However this hasn't been tested yet and should be tested before merging into main. Opening this issue to remind myself to test it later.

Can a web server be added to this library, similar to to the Arduino GSM library's GSM Web Server?

Thank you

GPS Data did not get to the indoor location. I have used SIM808 EVB-v 3.2.2 GSM/GPRS + GPS board.

It's apparently possible according to the command reference, but I'm not sure if it should be built in to Adafruit_FONA::readSMS() or a whole new method (like say boolean Adafruit_FONA::getSMSSender(uint8_t i, char *smssenderaddr).

AT+CFGRI=1 makes the FONA look to see if an Unsolicited Result Code (URC) should trigger the RI pin low for 120 ms. It doesn't have much to do with SMS's.

While trying to set APN information such as:

fona.setGPRSNetworkSettings(F("internet.com"), F("wapuser1"), F("wap"));

the following compile error occurs

Arduino: 1.5.6-r2 (Mac OS X), Board: "Arduino Mega or Mega 2560, ATmega2560 (Mega 2560)"

The code compiles fine when the last part of the call (password field) is changed to at least 4 characters long.. and MUST contain a space. Example:
fona.setGPRSNetworkSettings(F("internet.com"), F("wapuser1"), F("wap 1"));

Unfortunately i need the password to be 3 chars and NO spaces...

I can't seem to understand the problem to fix it...

it seems that when asking readSMS to read a slot which is empty, it returns false and sets readlen to 0 at the same time.
In the fonatest example, the detection for empty slots is a true response from readSMS and a readlen of 0.
Which one of the two is the correct one?
In the current version, when using 'R' to read all SMS, fonaTest wrongly stops reading all SMS too early if it encounters an empty slot...
